ROLLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 270,170, dated January2, 1853,

Application filed April 10, 1882.

State of Massachusetts, have invented certain Improvements inMetal-Rolling Machines, of

.which the following is a specication.

Thisinvention relates to rolls between which metal bars or plates arereduced by successive t passes through the rolls, which are adjustable,

so that the space between them can be increased or diminished.

The object of the invention is to provide an improved arrangement ofgearing connecting the ends of said rolls whereby anydesired adjustmentof the rolls can'be effected without a'ecting the gears.

To this end my invention consists in the improvements which I will nowproceedV to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure l represents an end elevation of a pair of rolls and theirsupporting-frame and connectinggearing embodying my invention. Fig. 2represents au elevation of the opposite end. Fig. 3 represents a rearelevation.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, A and B represent a pair of rolls, which are journaledrespectively in boxes G D, supported by a suitable-frame, E, the boxes Gofthe upper roll being vertically adjustable in slots in said frame, sothat the distance of the upper fromthe lower roll may be increased ordiminished.

S S represent screws, whereby said boxes C are adjusted and heldpositively at any position to which they may be adjusted. lhe screws S Sare preferably provided with gears F F, connected by an intermediategear, G, whereby the screws are rotated in unison.

The parts thus far described are of the common construction, and do notconstitute my invention.

Heretofore rolls which are adjustable toward and from each other havebeen connected, so as to be positively rotatedin opposite directions, bygears separate from the rolls, journaled in fixed supports, andconnected with the rolls by jointed couplings which are capa- (Nomodel.)

ble of a lateral movement to permit the distance between the-centers ofthe rolls to be varied. This connecting mechanism is cumbrous, noisy iuoperation, and occupies more space than is desirable, the gears whichimpart motion to the rolls being necessarily at a considerable distancefrom the ends of the rolls. Y

1n carrying out my invention I provide the roll A with a gear-wheel, g,and at the opposite end oftheroll B a gear-wheel, a, of the same size asg.

g h, represent, two shafts journaled in the frame E parallel with therolls A B.. The shaft g' has apiniou, b, meshing with the gearwheel ofthe. lower roll, and the shaft hhas a pinion,f, meshing'with thegear-wheel ofthe upper roll. The shaft g is provi-ded with a largegeen-wheel, c, which receives motion from the prime motor. The shaft his provided with a pinion,.e, which meshes with the pinion b of theshaft g rlhe roll B and shaft h are therefore rotated by the shaft y',and the roll A by the engagement of its gear-wheel with the pinion e onthe shaft h. The axial line ofthe shaft 71l is substantially in the samehorizontal plane as the axial line ofthe upper roll, A. As a result ofthis arrangement the upper roll is enabled to be adjusted vertically toa considerable extent withoutinterfering with the operative relationbetween its cogwheel g and the pinion fof the upper shaft,` the distancebetween Athe centers of the upper roll and upper shaft being butslightly altered by a considerable vertical adjustment of the roll.

If desired, the axial line of the upper shaft may be arranged in ahorizontal plane midway between the planes in which the axial line oftheupper roll stands atthe upper and lower extremes of its adjustment. Thisarrangement will reduce the extremes of variation between the gear g andpinion f(caused b v the adjustment of the upper roll) to the minimum.

lt will be observed that by my described imselves, and thus prevent in agreat measure enabled to make the gears on the rolls of con-.

siderably greater diameter than the rolls themthis liability tobreakage.

Although I have shown only two rolls in the present instance, it will beobvious that my invent-ion may be applied to three-high or four-highrolls, it' desired, an additional shaft and pinion being employed foreach additional roll, and all the shafts being geared together and eachto its own roll.

I claim- The combination ot' two or more verticallyadjustablc andindependently-driven metall rolling rolls, each provided With'acog-wheelat one end of its shaft, and a corresponding' numof fixed driving-shaftsarranged in front ofthe said rolls in separate housings and geared eachto the other'and to the common motor at one end and to the rolls at theother, whereby vertical adjustment ofthe rolls is permitted withoutinterference with the operative relation of the gearing connecting therolls and driving-shafts, substantially as described.

1n testimony whereof l have signed my naine to this specilieation, inthe presence of 3o two subscribing witnesses, this 28th day of March,1882.
